Dubbed Thunderstrike, because it spreads through maliciously modified peripheral devices that connect to a Mac's Thunderbolt interface. When plugged into a Mac that's in the process of booting up, the device injects what's known as an Option ROM into the extensible firmware interface (EFI), the firmware responsible for starting a Mac's system management mode and enabling other low-level functions before loading the OS. The Option ROM replaces the RSA encryption key Macs use to ensure only authorized firmware is installed. From there, the Thunderbolt device can install malicious firmware that can't easily be removed by anyone who doesn't have the new key.
About Paul Spoerry
I’m a groovy cat who’s into technology, Eastern Thought, and house music. I’m a proud and dedicated father to the coolest little guy on the planet (seriously, I'm NOT biased). I’m fascinated by ninjas, the Internet, and anybody who can balance objects on their nose for long periods of time.
I have a utility belt full of programming languages and a database of all my knowledge on databases... I practice code fu. Oh, I've also done actual Kung Fu, and have a black belt in Tae Kwon Do.
